This facet encapsulates the code to compare strings in a localized manner. The collate template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual functions. These virtual functions are hooks for developers to implement the behavior they require from the collate facet.

Member Function Documentation template<typename _CharT> int std::collate< _CharT >::compare (const _CharT *__lo1, const _CharT *__hi1, const _CharT *__lo2, const _CharT *__hi2) const [inline] Compare two strings. This function compares two strings and returns the result by calling collate::do_compare(). Parameters: __lo1 Start of string 1. __hi1 End of string 1. __lo2 Start of string 2. __hi2 End of string 2. Returns: 1 if string1 > string2, -1 if string1 < string2, else 0. Definition at line 642 of file locale_classes.h. template<typename _CharT> int std::collate< _CharT >::do_compare (const _CharT *__lo1, const _CharT *__hi1, const _CharT *__lo2, const _CharT *__hi2) const [protected], [virtual] Compare two strings. This function is a hook for derived classes to change the value returned. See Also: compare(). Parameters: __lo1 Start of string 1. __hi1 End of string 1. __lo2 Start of string 2. __hi2 End of string 2. Returns: 1 if string1 > string2, -1 if string1 < string2, else 0.

This function computes and returns a hash on the input string. This function is a hook for derived classes to change the value returned. Parameters: __lo Start of string. __hi End of string.

This function computes and returns a hash on the input string. It does so by returning collate::do_hash(). Parameters: __lo Start of string. __hi End of string. Returns: Hash value. Definition at line 675 of file locale_classes.h. template<typename _CharT> string_type std::collate< _CharT >::transform (const _CharT *__lo, const _CharT *__hi) const [inline] Transform string to comparable form. This function is a wrapper for strxfrm functionality. It takes the input string and returns a modified string that can be directly compared to other transformed strings. In the C locale, this function just returns a copy of the input string. In some other locales, it may replace two chars with one, change a char for another, etc. It does so by returning collate::do_transform(). Parameters: __lo Start of string. __hi End of string. Returns: Transformed string_type. Definition at line 661 of file locale_classes.h.
